Astley Green Colliery was a coal mine in Astley, Greater Manchester, then in the historic county of Lancashire, England. It was the last colliery to be sunk in Astley. Sinking commenced in 1908 by the Pilkington Colliery Company, a subsidiary of the Clifton and Kersley Coal Company, at the southern edge of the Manchester Coalfield, working the Middle Coal Measures where they dipped under the Permian age rocks under Chat Moss. The colliery was north of the Bridgewater Canal. In 1929 it became part of Manchester Collieries, and in 1947 was nationalised and integrated into the National Coal Board. It closed in 1970, and is now Astley Green Colliery Museum.

The Astley Green Colliery Museum is a museum run by the Red Rose Steam Society in Astley near Tyldesley in Greater Manchester, England. (grid reference SJ70509996) Before becoming a museum, the site was a working colliery that produced coal from 1912 to 1970; it is now protected as a Scheduled Monument. The museum occupies a 15-acre (6 ha) site by the Bridgewater Canal which has the only surviving pit headgear and engine house on the Lancashire Coalfield.
